Due diligence on an independent auto repair shop

Diligence on an independent shop under LOI is where a buyer confirms — or does not — that the reputation and relationships described in the listing actually belong to the business. Because an independent shop has no franchise brand standard to lean on, three findings matter more here than in a typical small-business review: what the shop’s repeat-visit data actually shows about customer loyalty, whether the shop’s licensing and registration status is what the seller says it is, and what near-term capital spend the equipment will realistically require.

Pull repeat-visit data and read it carefully

Request point-of-sale or shop-management system data broken out by customer over at least two or three years, and look specifically at whether repeat customers return regardless of which technician serviced their vehicle previously. A finding that a disproportionate share of repeat business is tied to a single technician — especially the seller — should change how a buyer prices the deal and how long a transition period they build into the closing, because that finding means the durable customer relationships are narrower than the topline retention rate suggests.

Confirm licensing status directly, not through the seller

Contact the relevant provincial regulator directly — OMVIC in Ontario, or the equivalent body in other provinces — to confirm what a buyer specifically needs to do to operate legally after closing, since provincial repair and dealer registration attaches to the registrant, not the business. Get any confirmation from the regulator in writing where possible, and build the buyer’s own application timeline into the closing schedule rather than assuming registration happens automatically alongside the paperwork.

Test equipment against current vehicle technology, not the invoice history

A shop’s equipment list on paper says little about whether it can actually service ADAS-equipped and increasingly electronic vehicles. Bring in a technician or equipment appraiser who does not work for the seller, request calibration and maintenance logs for every major piece of equipment, and treat any gap between what the shop can service today and what the local vehicle parc requires as a live negotiating point rather than a footnote.

Confirm environmental exposure independently

Any shop that has handled waste oil, solvents, coolant or refrigerants, or that has any history of underground or aboveground storage tanks, carries environmental exposure that will not appear on a balance sheet. A Phase I environmental site assessment, escalated to a Phase II if the first flags a concern, gives a buyer and their lender a documented picture of what they are taking on and surfaces issues while there is still room to negotiate or walk away — waiting until after closing to find a legacy contamination problem is dramatically more expensive than finding it during diligence.

Check the shop’s online reputation against what the seller claims

Because an independent shop’s whole value rests on customers trusting its name rather than a franchise brand standing behind it, a buyer should read the shop’s public reviews, complaint history and any regulator-facing consumer complaints directly, rather than relying on the seller’s summary of its reputation. A pattern of recent negative reviews, a spike in complaints in the months before a listing, or reviews that consistently praise one named technician rather than the shop as a whole are each a different kind of warning — the first suggests declining service quality, the second suggests a seller cutting corners on the way out, and the third confirms the customer loyalty this business depends on may not transfer with the sale.

Verify financial records line by line

Reconcile several years of financial statements, tax filings and bank statements against each other rather than accepting a single seller-prepared summary, and look closely at labour versus parts revenue and at every add-back the seller has proposed. Bank deposit records reconciled against point-of-sale data are one of the more reliable ways to confirm that reported revenue actually reached the business rather than being adjusted after the fact.

Map exactly how dependent the shop is on the seller

Identify whether the shop’s revenue rests heavily on the seller’s own technical work or personal customer relationships, and ask directly whether other technicians and staff intend to stay through and after the transition. A finding that the shop’s scheduling and customer-communication systems exist mostly in the owner’s head, rather than in software any employee can access, is a genuine transition risk that should factor into both price and the length of any post-closing transition period.

Review the lease and any assignable supplier accounts

Confirm whether the lease can actually be assigned to a buyer, whether landlord consent is required, and what condition the space needs to be returned in if the lease ever ends. Do the same for supplier accounts and any equipment leases — provisions that look routine sometimes carry assignment restrictions that only surface once someone reads them closely, and a shop that has invested in bay doors, lifts pits or drainage built into a leased space may not automatically own those improvements once the lease ends.
